How to Build a Smart Dustbin Using Arduino – Step-by-Step

Introduction

Do you have a picture of a dustbin that opens automatically whenever you walk by it? It’s called a Smart Dustbin Using Arduino. It is powered by sensors, and you don’t need to handle it with your hands. This makes everything neat, secure, and safe.

On this page, you’ll discover what a smart dustbin is, the reason we require to have one, how it operates, and the components required, including the circuit and codes, as well as the step-by-step procedure to construct one. The entire process is explained in easy language so that even elementary school students will be able to understand the concept.

What Is a Smart Dustbin?

The smart dustbin is a kind of dustbin that opens the lid automatically if a person is near it. It is not necessary to reach out and touch the dustbin. It utilises an ultrasonic sensor to sense your hand and then makes use of a servo motor to lift the lid.

This entire setup is known as a Smart Dustbin Project and is extremely popular for engineering students at schools, school students, and even project competitions.

Why Do We Need a Smart Dustbin?

We need smart dustbins because:

• It helps keep our hands hygienic.
• It can help prevent infection and germs.
• It makes the process of disposing of waste modern and enjoyable.
• It’s extremely useful in hospitals, schools, office buildings, homes, and homes.
• It helps save time and also makes hygiene automatic.

This is the reason why the Automatic Dustbin project is among the most beneficial technological projects for novices.

How Does a Smart Dustbin Work?

The operation of a smart bin is quite easy:

1. This ultrasonic sensor examines whether something is close to the garbage bin.
2. When your hand gets close to the sensor, it detects the distance.
3. The Arduino gets signals from sensors.
4. Arduino transmits a signal to the motor’s servo.
5. The servo motor spins and lifts the lid.
6. After a couple of seconds, the motor closes the lid.

This is how automated opening and closing happen in a smart garbage bin. You don’t need to handle anything.

Key Components Required for a Smart Dustbin Using Arduino

To complete this project, it is necessary to have a few basic components. They are readily available in any electronic shop or on the internet.

1. Arduino Uno

It is the brain that runs the whole project. It is the one that controls everything.

2. Ultrasonic Sensor (HC-SR04)

The dustbin’s sensor can detect your hand or any other item.

3. Servo Motor

The motor helps shut and open the lid.

4. Jumper Wires

The wires are used to connect the various components to the Arduino.

5. Breadboard 

It is used to make smooth and tidy connections, without soldering.

6. Dustbin

Any plastic dust bin of any size can be used. Visit our blog to learn about the " Smart Dustbin Using Arduino"
